Okay, from my perspective (68 + and 7 handicap), I find that both the MProject spiked and spikeless give me essentially equal traction. I've worn both in both wet and dry conditions and have not had any difficulty with either one. In fact, the first time I wore each of my pairs, play was cart path only due to recent rains and I found both types equally comfortable. Just this week, I chose to wear my spiked version because of wet conditions. The only time I had any slippage was when attempting to get solid footing in a creek bed (hazard) that was really muddy. I simply adjusted the placement of my feet and proceeded without any problem.
